There were a total of 54 questions in a school English test. 10 marks were awarded for each correct answer and 7 marks were deducted for each incorrect answer or incomplete answer. Ivory could not complete all the questions in time and left the last 4 questions blank. She scored 132 marks. How many less wrong or incomplete answers than correct answers did she answer?

Correct answers	Marks awarded (x10)	Wrong or incomplete answers	Marks deducted (x7)	Difference
50	500	4	28	472
49	490	5	35	455

Number of questions completed
= 54 - 4
= 50

Big difference
= 472 - 132
= 340

Small Difference
= 472 - 455
= 17

Number of wrong answers
= 340 ÷ 17
= 20

Number of wrong and incomplete answers
= 20 + 4
= 24

Number of correct answers
= 54 - 24
= 30

Number of less wrong or incomplete answers than correct answers
= 30 - 24
= 6

Answer(s): 6
